Description

This was a customer upgrade from Ambari-2.2.2 to Ambari-2.4.2. We should investigate why the behavior is different for hosts with ambari-server. It's better to have the same PYTHON_PATH or library resolution scheme for the agent irrespective of the host it is installed.

[root@c6401 vagrant]# yum list installed | grep ambari
ambari-agent.x86_64    2.4.2.0-136      @Updates-ambari-2.4.2.0
ambari-server.x86_64   2.2.2.0-460      @Updates-ambari-2.2.2.0
